A recent change in GCC caused a regression for moxie-elf-gcc. Here's an
updated version of the port. The only change in this version is the
addition of the last switch statement case in
moxie_print_operand_address() in gcc/config/moxie/moxie.c.

It's been a few weeks since I submitted the last final version of this
patch. I'll let this updated patch act as my PING to the people who can
approve this port.
